Tungsten Carbide Nozzle Spark Plasma Sintering Technology

Spark plasma sintering (referred to SPS) is a kind of progress that put metal powder into the mold made by graphite and other materials, which uses the upper and lower punches to excert energized electrodes and particular sintering pressure to produce high performance material after discharge activation, thermoplastic deformation and cooling. SPS process and hot pressing (HP) have some similarities, but the heating mode is completely different, which uses DC pulse current pressure sintering to sintering directly. In general, DC pulse current plays a significant role in generating discharge plasma, the impact of the discharge pressure, Joule heat and the diffusion of electric field.
